The Mach3 USB interface board requires 24V relays externally. There are no relays on the mach3 usb board. If you use an external relay on the mach3 usb board, the relay connects to the V+ which is 24V and the output pin is the return.

Additional Information:
I understand what you are saying. Does your relay board work with the Mach3 USB board? If not, what relay board do you suggest to work with this usb controller?

Additional Information:
Our relay board works with our parallel breakout board. An off the shelf SSR (Solid State Relay) made for 24V should work fine.

I bought a 'BuildyourCNC V1' relay board to go with my mach3 usb controller. I have been sent a 'Songle' relay. It's not the one in your picture and it's got different connections, for which there isn't a wiring diagram. The one I ordered says it is 5v, this one seems to be saying it's a 24v unit. Can you please explain what has happened? Thanks

I am having difficulty with the wiring on the White Ant. The latest electronics that I received don't seem to be anything like the book or even the tutorials. For instance, the three stepper drivers need 6 pin connectors and ribbon cable. How are they wired? There was no thermocouple wire included. Thanks,

There is a multitude of methods to create the table and frame for the greenBull long-z CNC machine, as some of the illustrations are shown on our gB webpage.

The image with the hollow mid section, is a custom table that will take advantage of the entire long-z axis assembly. So the frame can be built in that manner, however the CNC table should have its 3/4" table top. So you can cut standard sheets of wood, aluminum, plastics, etc.

So that specific illustration is not needed, however if you plan on cutting at that depth then it will defiantly benefit you to have that frame as shown in the illustration!

Can you please clarify what a long Z axis table should look like? I've built a frame that matches the dimensions on the GreenBull page but under long Z it says a custom frame is required made out of steel, which I did. But do I need to have the frame open like shown in the picture or is that just showing what the table looks like under the 3/4 material?

The upper right hand corner of the data sheet found at https://buildyourcnc.com/Documents/PN.SM86HT80-5504B-U(inhouse%20PN.85BYGH450A-47-80)%20(1).pdf labels the coil wires A-D and also by color, which refers to the colors coming off of the motor. Our specification for A+, A-, B+, B- follows the labeling of the driver connections where A+ is coil A's positive lead and the same for the B coil. If you find yourself wiring 4-wire stepper motors without a datasheet, you can easily determine which colors go together with an ohmmeter. Each pair associated with the same coil will have continuity (negligable resistance) between them.

Wiring the greenBull stepper motors, in the video you say to look at the data sheet for the motor, which is the 651, in the data sheet it shows A, B, C, D, for the colors, and in the video you say A+, A- and so on. Is there a video for wiring the connection to the RedFly that I bought to better explain what I need to do next. I'm using 16c4 SO cord, so I can match color to color on the motor side.

The board layout is different and the terminals have slightly different names, but the two boards function the same. The wiring diagram is the same for both boards. The plug-in driver for Mach3 is also the same, so you should not have a problem. If you do run into an issue, please let me know here and I will help you determine the problem.

Thanks

Additional Information:
Thank you for the assurance that the boards will function the same. You did not answer the primary question of wiring. The diagram shows a board with a 5V for each axis, the new boards have only 1 5V point on the axis side. In retrospect since this controller receives information and most possibly the 5V signal directly from the computer leading to the drivers. I will wire the X, Y and Z axis to the single 5V point and see what happens.

received my mach 3 USB breakout board today. The layout of the board is different from your diagram which shows a 5V power slot for each axis. Do I wire the 5V slot with only one 5V wire from one of the drivers or perhaps wire all three 5V wires into the one 5 V slot. Please advise.

The Mach3 USB controller requires a minimum of 12V and a maximum of 24V to the DCM and 24V terminals. The DCM is the GND or DC negative terminal, and the 24V terminal is the positive terminal.

I bought the Mach3 board and am trying to connect it with an AMB 1400 DI router, which has a normal power supply (1400W) as well as a digital interface which has three wires: a brown wire (10-26V, power supply), a white wire (ground) and a green wire (0-10V signal). I'm no electronics guy--how do I connect the digital interface of the AMB to the Mach3 board?

The space allotted for the laser tube on the blackTooth would not allow for a higher power laser tube. As the wattage of the laser tube increased, so does the length of the tube.

We do have a larger and more powerful laser in design and should be available in the second quarter of 2015.

Click the link to add information to this solution:
Can you install a more powerful laser/tube for us if we pick the $2100 option to have you build it? It would be assumed that there would be a new price for the machine which would reflect the cost increase for the new laser. Please say yes, I know you can physically do it. I have faith in you

You will need PlanetCNC software for the USB breakout board and when plugging in the USB the computer should automatically recognize the board, however you can go into device manager to see if the USB terminal is working correctly.
The parallel breakout board; the USB is not a connection terminal rather than a power source, and the parallel port will be the communication terminal.
The items you will need for a water cooled spindle would be: water pump, silicon tubing(length desired by customer), a extension cord(from a hardware store(orange))(1 same gauge wire/length as extension cord).

Not a problem. The ALM is rather self-explanatory as this is a closed-loop stepper motor and driver that you are using. The ALM (alarm) is a signal that is used to tell the driver/controller that the motor is not in the same condition that the driver expects. In a closed-loop system, the motor has an encoder that tells the driver exactly how many steps that it turned, and if this value does not coincide with the driver's outputted number of steps, and within a specified amount of time, the alarm will trigger so the system can stop and the workpiece can be salvaged.

The MF is simply a signal that tells the driver that there is impending direction and step pulses coming. If the MF signal is high, then that is similar to an enable signal.

Hello I recently read your site and have a question. I have a driver model DM2722A but I can't connect it to my usb controller due to the fact that the driver is not marked enable, but instead it is marked: mf-, mf +, alm-, alm +. I will be very grateful if you explain to me the meaning of the latter and tell me what should be related to "enable" Thanks in advance!

I purchased the driver boards and MB shield for the White Ant. None of the headers are labeled. Is there a diagram showing which headers is for which axis? Is there also a diagram showing which pin on the driver is ABCD? I have watched the vids and the boards in them do not match what was sent to me.

The electronics can be tricky sometimes, especially if more than one change is made for a test. You can move the x-dir wire to another pin and set it in the software configuration. If it works, then only that pin is bad.

We just received our new inventory of motors and that specific stepper motor ski came back with only one shaft. I’m not at the office to look at this inventory, so if that is true, they will all be single shaft. We may have other stepper motors with included rear shafts, but I will have to see on Monday.

If I don’t have the double shaft, we will provide a refund upon receipt of the motors. My apologies for this error.

Additional Information:
Hi, I'm sending these motors back today. As I understand you, you might have some motors from the previous lot still in stock, and these would be double shaft but otherwise you don't have any and won't be getting any. If you do have two double shaft versions of this motor please send them; if you don't have two of them please let me know--today if possible--so I can start looking elsewhere. Thanks, Ted Armen

we just received two nema 11 stepper motors per our order--USR2-2, however they are single shaft, we need double shaft, I thought that's what we ordered. We're sending them back, let me know if you do have the double shaft version and I'll try again to order them. I notice the model number on the motor ends in "A", where the packing slip shows "B".

There is some variation in the outward appearance of laser power supplies due to sourcing through different vendors. However, the basic wiring requirements are the same in each case. For the unit with integrated laser controller, follow the diagram found here: https://buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx#prettyPhoto/0/. The terminals on the signal side will have a 6 connection terminal block -- these are the ones labeled 5V, IN, G, P (or WP), L (or TTL-L), and H (or TTL-H). The High Power side will have 3 inputs for AC power, one high voltage lead, and one return line. Connect these as shown in the diagram as well: the return line goes on the "front" (beam exit end) terminal of the laser tube, the high voltage lead goes to the "back" terminal of the tube, the FG terminal (or G) receives the earth ground wire of the AC power cable, and the two AC terminals receive the line and neutral wires of the AC power cable (it doesn't matter in this case which wire goes to which terminal).

The 5x10 greenBull base kit comes with the structure, hardware, and electronics for motion control. In order to have a fully functional CNC you will need a table base for your machine, a spindle or router to handle your cutting applications, end mills (bits) for cutting, CAD, CAM and CNC software, and a computer. There are also accessories you can add such as limit switches, emergency stops, and cable carrier for cable management.

It generally does not matter if it is longer at the other end as long as the lead screw provides the desired travel for that axis. The lead screw will only need to be long enough for the travel, plus any structure and lead-nut positioning.

For example:
- The motor that will turn the lead screw will need to be mounted at some position (generally at one end of the axis). In many cases, this positioning will be mounted where some of the lead screw will not be used (the lead nut will not be able to moved close to the coupling of the lead screw to the motor shaft). Add some of the length of the lead screw to be inserted into the coupling.

- If the lead screw will contain bearings at either end of the travel, that portion of the mechanical assembly will need to be considered in the lead screw length.

- The lead-nut will need to be mounted in a position on a structural member of the part that is to move. The distance from the part of the structure that will extend closest to the motor will have some distance to the position of the lead nut. This distance will need to be added to the lead screw length.

Add these discrepancies to the length of the lead screw and the travel length and you will have the final length.

What laser controller model number do you have?

Additional Information:
Hey - the model number on the laser controller is
AWC708C
S/N:708014243

Additional Information:
Thanks for the model number. I am going to fabricate the parts and put it together myself to see the issue. We made this modification to the blackTooth laser cutter to better house the new laser controller that we wanted to add to the laser, but that may have been for the AWC608. If there is an issue with my assembly, we will create a new part that will correct the issue and send it to you.
